Can you customise the buttons and zippers on a sweater?

Yes - corozo, metal (with engraved logo), horn and resin buttons, plus YKK and metal/coil zippers with branded pulls. Send a reference or sample and we match it.

Can I nominate my own trims or hardware supplier?

Yes. We apply buyer-nominated hardware (for example YKK or custom-engraved buttons) during production; nominated trims may carry their own minimums and a little extra lead time.

Is there a minimum order for custom trims?

Standard trims fit our 30 pcs per colour MOQ. Custom-engraved buttons or branded zippers may add a supplier minimum and a few days of sourcing.

What does Licheng Knitwear manufacture?

We focus on men's sweaters, cardigans, knit jackets, jacquard knitwear and private label knitwear. We support B2B buyers with OEM/ODM development, sampling and bulk production planning.

Do you support low-risk trial orders?

Ready sample styles and selected custom programs can support lower-risk trials before larger seasonal orders.

Q: What trims can you add to knitwear?

Buttons, zippers, drawcords and cord-stops, suede or knit elbow patches, contrast tipping on collars and cuffs, and custom rib trims.

Custom buttons, zippers, drawcords, patches and tipping sourced and applied to your spec — the fiddly hardware requests other factories decline, we quote and make.

Technical Details

Buttons: corozo, metal (engraved logo option), horn / faux-horn, resin and shell, colour-matched to the yarn. Zippers & closures: YKK and metal/coil zips with branded or custom pulls, antique/gunmetal finishes, toggles and cord-stops. Other trims: drawcords with custom tips, suede or knit elbow patches, contrast tipping on collars/cuffs/plackets, and custom rib trims (stripe or colour). Trims are sourced to your spec or supplied by you (nominated supplier), then attached during linking/finishing.

Trims carry their own compliance exposure, which is why they are specified and tested separately from the knit. Metal components in prolonged contact with skin — zip pulls, sliders, rivets, metal buttons — are controlled for nickel release under REACH Annex XVII entry 27, tested to EN 1811 (with EN 12472 simulating wear and corrosion on coated items), so a decorative finish does not exempt a component. Azo colourants that can release restricted aromatic amines are controlled under REACH Annex XVII entry 43, which applies to dyed cords, tapes and woven labels as much as to yarn. For children's programmes the additional constraints are CPSIA lead and phthalate limits and the small-parts and mechanical-hazard requirements under 16 CFR 1501, which is what governs whether a button or toggle can be used at all on a given age grade. Accessories can be brought inside an OEKO-TEX Standard 100 certified article rather than sitting outside it, provided the trim supplier holds the corresponding certificate. Nominated branded hardware such as YKK is sourced to your spec, and pull-off strength on buttons and attached trims is checked against the knit's stretch before bulk.

Production Notes

Share a reference photo, sample or tech pack with the trim spec (material, size, finish, logo). Nominated/branded hardware (e.g. YKK, custom-engraved buttons) may carry its own minimums and add a few days to sourcing — factor it into the sample timeline. Trims are checked against knit texture and garment stretch before bulk.

Order of operations that prevents a late failure: agree the trim spec (material, size, finish, logo) with a reference photo, sample or tech pack; confirm whether the item is nominated or open-sourced, since branded hardware carries its own minimums and adds days to the sample timeline; request the trim supplier's EN 1811 nickel-release and REACH Annex XVII declarations at the same time as the price, not after approval; and for children's styles confirm CPSIA and 16 CFR 1501 suitability before the button is designed in. Trims are checked against knit texture and garment stretch, and attachment strength is verified, before bulk.
